This morning I was trying to come up with some good problems for students to use to find local maxima and minima. It's an awesome feeling to be able to combine everything I know about graphs and polynomials and end behavior to create polynomials within the window that I want that do what I want. It's cool to think that I don't have to just guess random things. So the graph is too long and skinny? I can do a vertical compression or a horizontal stretch. I want two local maxes and one local minimum, so I know I need to give it a negative leading coefficient and an even degree. It might be neat to come up with some sort of guidelines and have the students come up with their own polynomials. I wouldn't want them to just guess and check though. I might have them write something that says what they would have to do to a graph to get the desired results. It really forces you to use everything you know about polynomials and graph behavior and actually apply it.
I've been thinking about second chances constantly lately. As an adult, think about all the times you've been given a second chance. I am not a perfect wife, but my husband gives me second chances all the time. I tried to make cookies once with baking soda that was 2 years expired. They didn't turn out so great, but I have had other chances to bake things and I learned a value lesson about baking soda : ) I tried out for my church praise team and didn't make it. It was embarrassing and for a while I didn't feel like singing or playing the piano, but I can try out again and if I don't get so nervous next time, maybe I'll make it. I'm not banned forever because of one audition. I took the ACT twice when I was in high school, and my highest score was the only one colleges cared about. My first year of teaching, I struggled quite a bit with classroom management. I needed more time and unfortunately first-hand experience to just begin lea...
